He attended Public School 96 in the Bronx, New York, and junior high at Public School 89. He moved on to Stuyvesant High School in New York City and then transferred to his local high school, Christopher Columbus, midway through his junior year. After graduating from high school, Bernie enrolled at the City College of New York and at the end of his junior year, in 1954, Bernie married Ruth Ochs. In 1956, Bernie graduated from the City College with a Bachelor of Mechanical Engineering degree and commenced his graduate studies at Columbia University. Bernie obtained a Master of Science degree in 1958 and a Ph.D. degree in mechanical engineering in 1962, studying under the mentorship of Professor Ferdinand Freudenstein [1,2] . 2. Career In the fall of 1962, Bernie and his family left New York for California to commence his academic career in the Design Division of the Mechanical Engineering Department at Stanford University. Fig. 1 is a photograph of Bernie in the 1960s a few years after his arrival at Stanford. He was promoted from the rank of Assistant Professor to Associate Professor in 1967 and then to Professor in 1972. Some of the courses that Bernie has taught at Stanford over the years include: kinematics of mechanisms; kinematic synthesis of mechanisms; advanced kinematics; mechanics of robots; mechanical engineering design; analytical methods in design; computer-aided design; applied mathematics; technology and society; the role of the designer in society; transformative design; educating young STEM thinkers; and design and creative problem solving. The Stanford Artificial Intelligence Laboratory (SAIL) was founded the same year that Bernie arrived on the Stanford campus. This ∗ Corresponding author:. E-mail address: [email protected] (G.R.

Pennock, P. Flores / Mechanism and Machine Theory 0 0 0 (2017) 1–5 Figure 1. Professor Roth (circa 1968). was a center of excellence for artificial intelligence research, teaching, theory, and practice. Bernie became heavily involved with the research activities conducted at SAIL and ensured that everyone there was interested in robotics. Although his primary interest was kinematics, he had a strong background in computer science and programming. He was the faculty member in the Mechanical Engineering Department who had the most in-depth involvement with robotics. Bernie was known as the professor who would go out of his way to advise and assist the research students working in the laboratory. During his early research years, Bernie developed an efficient numerical method for solving systems of nonlinear polyno- mial equations, which he called the bootstrap method that presaged what are now known as the continuation or homotopy methods. He also focused his research activities on an investigation of the mathematical theory of rigid body motions and the application of these motions to the kinematic synthesis of mechanisms. He placed a special emphasis on geometric kine- matics over the more traditional time-based formulations, which allowed him to make important contributions to Burmester theory, curvature theory, and screw theory. Bernie deserves much of the credit for the modern development of Burmester theory, which began with his doctoral thesis that focused on a generalization of the classical theory. In 1967, Bernie de- veloped the spatial analogue of planar Burmester theory and for this original contribution to the science of kinematics he received the ASME Melville Medal, which is the highest ASME honor for the best original paper published in the ASME transactions during the two calendar years immediately preceding the year of the award. In 1968, Bernie spent his first sabbatical working with Professor Oene Bottema at the Technological University of Delft, The Netherlands. Their collaboration led to several technical papers and the book Theoretical Kinematics , which was pub- lished by the North-Holland Publishing Company in 1979 [3] . The global family of kinematicians regard this publication as one of the most elegant and rigorous treatments of the science of kinematics. Bernie has made significant and pioneering accomplishments in teaching, research, and consulting on various aspects of mechanical engineering, with a special focus on mechanism design and the mechanics of robotic manipulators. He has established a worldwide reputation as a researcher in the kinematics and design of mechanisms and computer controlled mechanical devices. He was a pioneer in the field of robotics with a special focus on the kinematics, mechanics, and control of robot manipulators. 3. Major awards Bernie received the American Society of Mechanical Engineers (ASME) Machine Design Award in 1984. The award rec- ognizes eminent achievement or distinguished service in the field of machine design, which is considered to include ap- plication, research, development, or teaching of machine design. Two years later, Bernie received the Robotic Industries Association Joseph F. Engelberger Robotics Award (the most prestigious international robotics honor), which is presented Please cite this article as: G.R. Pennock, P.

Memorial Tributes: Volume 15 FERDINAND FREUDENSTEIN 1926–2006 Elected in 1979 “For leadership and research in kinematics and design of mechanisms.” BY BERNARD ROTH SUBMITTED BY THE NAE HOME SECRETARY FERDINAND FREUDENSTEIN, longtime Columbia University mechanical engineering professor who is considered the father of modern kinematics in America, died on March 30, 2006, at the age of 79. Ferdinand Freudenstein was born into a Jewish family, on May 12, 1926, in Frankfurt am Main, Germany. When Ferdinand was 10 years old, he, his parents, and two sisters fled the Nazis for safety in Holland. In the spring of 1937, after six months in Amsterdam, the family moved to England, where they joined his brother, who was studying there. They lived in London during the Blitz, moved briefly to Cambridge, and then spent several years in Llandudno, North Wales. During this period his father and brother, were sent into exile in Australia, since the British government regarded all adult male German citizens, even victims of Nazi anti-Semitism, as enemy aliens. In 1942, when he was 16 years old, Ferdinand, his mother, and one sister sailed on an old British cargo boat from England to Trinidad. They remained there for six weeks until a distant cousin arranged for their visas to the United States. They arrived in New York harbor in March 1942. Ferdinand had a high school equivalency certificate from Wales and was able to enter college at New York University. He spent two years studying there and then at age 18 joined the U.S.

Waldron Professor (Research) Emeritus, Stanford University, and Professor, University of Technology, Sydney Abstract: This paper comprises a review of Bernard Roth’s technical contributions and contributions to his professional community. Particular attention is paid to his role in the establishment of the unique design program of the Department of Mechanical Engineering at Stanford University. Another theme is the creation of one of the very first research programs in digitally controlled robotics in the Stanford Artificial Intelligence Laboratory. No review of Roth’s career would be complete without touching on the numerous fundamental contributions to research in linkages and robotics. At the same time it is not possible in a work on this type to examine every one of his publications and other contributions. We have endeavored to select the most important, but that is, of course, a personal judgment. 1. Introduction Over a career that has now spanned 55 years at Stanford University, Bernard Roth has influenced many areas of machine design and robotics, and also creativity and self- realization. This paper constitutes a review of that career by one who was in a position to witness much of it first as a doctoral student supervised by him, then as a fellow researcher in the same general field, and more recently as a colleague in the same academic unit.
